Quoting Gringat the Repugnant
Interesting look! I think he'd be doubly improved if you were to give him large claws on his upper sets of arms and give him the ability to walk on all-sixes as well as walk upright like he is doing, though. It seems natural for him to do both.
Thanks! Unfortunately, this one is a pretty old MOC, so I disassembled him long ago. And as I never make plans, it would be pretty hard to re-assemble him... :-( Besides, I have too many projects to even think of re-building an ancient MOC. :D
